英文摘要	Nutrient deficiency is a limiting factor in saline-sodic soils resulting in low crop production. The study investigated wheat response to P and K added to soils. The K was applied at 0 (K0), 75 (K1), 150 (K2) kg K2O ha(-1) as K2SO4 and at (0 (P0), 60 (P1), 120 (P2) kg P2O5 ha(-1) as (NH4)(2)HPO4 in three replications under two-factorial randomized complete block (RCB) design. Both treatments significantly enhanced wheat grain (118%) and dry matter yield (60%) at P2K2 compared to control. The P treatments significantly affected leaf P, Mg, SO4, Ca:P, SO4:P ratios and soil P, Ca:P, Cl:P and SO4:P ratios, while K on leaf K, Na, Ca, SO4 concentration, K:Na, K:Ca, SO4:P,Ca:P ratios and soil pH, Na, K, Ca, SO4 concentrations, SAR, Na:K, Ca:K and Na:Ca ratios. Leaf Na was decreased to 85.3 mmol (+) kg(-1) at K2 compared to 105.3 mmol (+) kg(-1) at P2K0. Negative correlation (R-2=0.906) of leaf K:Na was found with leaf Na concentration. The correlation of dry matter was higher (R-2=0.851) with leaf K:Na ratio than grain yield (R-2=0.392). It is concluded that the addition of K and P addition shows beneficial effects in improving crop nutrition and wheat yield in the saline-sodic soil environment.
